In a ruling that could have profound implications for enforcement of the city’s Smoke-Free Air Act, an administrative court judge has snuffed out charges of ashtray possession against Brooklyn Heights video store owner Marty Arno.

As reported in The Post, Arno had faced a fine of up to $2,000 for possessing that most villainous of inanimate objects: an ashtray (in this case, a souvenir from the classic 1984 B-movie, “The Rosebud Beach Hotel”).

At a hearing yesterday, Arno argued he had the ashtray simply to allow smoking customers to snuff out their illegal tobacco without having to leave the store.

Judge Stanley Trattler accepted that argument.

“I dismissed it on the grounds that it wasn’t used as an ashtray,” Trattler told The Post.

Although Trattler did not rule on the legality of the city’s anti-ashtray law, the decision may blow smoke on ashtray summonses.

Dozens of bars and restaurants have received an ashtray summons.

“Non-food” establishments like Arno’s video store are inspected only if the Health Department receives a specific complaint.
